Sourdough is the oldest form of leavened bread, dating back to at least 2000 B.C. when ancient Egyptians likely discovered it by accident. Wild yeast and bacteria may have drifted into dough left out to rest, triggering fermentation. The result? A naturally leavened bread with better flavor, texture, and—as we now know—several health benefits.
The fermentation process enhances digestibility and boosts fiber content. Some people with nonceliac gluten sensitivity may find sourdough easier to tolerate since fermentation helps break down gluten proteins. However, not all sourdough is created equal—it’s important to choose traditional, long-fermented varieties to reap these benefits.
